Campagnolo Chorus 12x Carbon Crankset, 172.5mm 34/50t, Black

Chorus 12 Speed Ultra-Torque Crankset

The new Chorus crankset is a true concentrate of technology and versatility. Technically advanced thanks to unidirectional construction technology in carbon fibre, it is directly moulded without any surface coating and has an Ultra-Torque steel axle like the Record crankset. The new 12x cranks are more versatile thanks to the new bolt pcd of 123mm, giving it an extremely solid structure, also ensuring a wider variety of uses. The new smaller bolt circle on the Chorus crankset makes it compatible with 36/52, 34/50 and the brand new 32/48 ratio chainrings.
Available in crank lengths; 170mm, 172.5mm and 175mm
